Page 2 Connectivity Overview Telephony The system supports standard PSTN lines connected to the Gateway via RJ11 jacks. PSTN lines should be provisioned as “loop-start”, Touch-Tone lines and if desired, the only features that should be provisioned on the PSTN lines are Caller ID, Line Hunting or Rollover. IT The customer site must have an Ethernet LAN and Internet connection. All elements of the LAN must be able to handle the additional IP end points. All AT&T SMB Telephony components must be on the same subnet and can not be connected via Wi-Fi.

Page 3 System Overview The system operates as a PBX. Users dial 9 to access outside lines. Calls are represented at the phone as call appearances rather than line appearances, as in a key system. There are two components to the SMB Telephony System (PSTN Gateway and Deskset) and two optional accessory devices (Cordless Handset and Cordless Headset).

(2) Phone line must remain intact (to take advantage of the microwatts needed from the offsite back up generator to power phones when the power goes out). The SB67010 PSTN Gateway provides connectivity between the internal Ethernet LAN where the phones are connected and the external PSTN lines. Each Gateway supports up to 4 PSTN lines and 4 Gateways can be combined to support up to 16 PSTN lines. There is no capacity relationship between the number of Gateways and the number of SB7030 Desksets on the system. A single Gateway can accommodate up to the maximum capacity of 50 Desksets. The number of Gateways needed is purely a function of the number of outside lines needed by the business as dictated by their call traffic. Since all incoming outside calls come through the gateway the Automated Attendant is also housed in the Gateway. The Gateway also has the ability to automatically switch one dedicated PSTN line to an attached, optional single line phone such as an AT&T TR1909 in the case of a power failure. Unlike a traditional KSU or PBX, the Gateway is not responsible for being the source of all system functionality.

The Deskset requires a power connection and an Ethernet connection. The Ethernet connection can be shared with a user’s PC by way of a separate Ethernet pass-through jack on the Deskset. This pass-through can support up to 100Mb Ethernet speeds to the attached PC, but will not support other data devices such as servers, switches and hubs or daisy-chaining additional Desksets. The SB67030’s 5-inch backlit display keeps the user informed on the status of up to 5 active or held calls, the number of missed calls and new messages and simple visual navigation and use of the Deskset’s features. Softkey operations present the user with the most likely options for each operational state the phone may be in; idle, active call, call on hold, etc. A portion of the display is reserved for context sensitive help text that guides the user through feature operations such as transfer and conference on a step-by-step basis. The Deskset also has an extensive built-in help menu that can answer many questions without referring to the user documentation. A unique feature of the SB67030 is its built-in DECT 6.0 base radio. This makes it possible for each Deskset to directly support one paired mobile handset (duplicating the Deskset extension number, name, and most features of the Deskset) SB67040 Cordless Handset (see next page) and TL7600 Cordless Headset which interoperates with the Deskset without the use of a lifter. This allows the business to accommodate individuals needing workplace mobility without the expense of deploying access points throughout the facility. The Deskset stores 30 minutes of voic messages which are clearly displayed on the screen allowing the user to selectively hear messages in any order desired. It also stores 50 names and numbers in a personal directory, 100 names and numbers in a system-wide directory, and recalls the last 50 incoming calls and the last 20 outgoing calls for easy access. Cordless Note: Due to the number of channels available on DECT 6.0, no more than 5 Desksets can have paired cordless devices.

SB67040 Cordless Accessory Handset The SB67040 DECT 6.0 Cordless Accessory Handset can be registered to any Deskset to become the Deskset’s paired mobile handset, sharing the same extension number and user information. The Cordless Handset duplicates most of the functionality of the SB67030 Deskset for workers who are frequently away from their primary work areas. Any calls directed to the user’s extension will ring at both the Deskset and Cordless Handset. The SB67040 has a speakerphone capability, corded headset support and a talk time of up to 5 hours from a full charge.

Page 7 TL7600 Cordless Headset The TL7600 Cordless Headset can be registered to any SB67030 Deskset providing the user with private, hands free operation. Calls can be answered and terminated from the Headset without the use of a handset lifter. The user can also control receive volume and microphone mute with the Headset’s controls. The TL7600 supports up to 9 hours of talk time. Headset Features Lightweight Comfortable Design Extended Range – Up to 500 Feet * Extended Battery Life – Up to 9 Hours Sound Level Protection Multiple Wearing Styles: – Over the Ear – Over the Head – Behind the Neck * Open range test was performed by Wyle Laboratories, an independent commercial test facility. “Up to 500 feet” cordless headset ranger refers to the maximum open field range. Actual range may vary depending on intervening obstacles. Maximum operable range distances are based on all-indoor use.

Page 8 Installing the SMB Telephony System Connect Deskset to Ethernet Connect Gateway to Ethernet and Phone Lines The first Deskset to power up and be connected to the ethernet network will become extension 200 and will be the default Operator extension. The Operator designation can be changed to any other extension later. As subsequent Desksets are connected, they will become extensions 201, 202 and so on. Extension numbers can be overridden to any 2xx number.

9
Page 9 Web User Interface – Phone Settings Basic Settings allows the administrator to add a name to an extension, override the extension number with a different number, set the number of seconds before forwarding and assign forwarding targets (VM, Extension, outside number). Station Directory allows the user to enter up to 50 names and phone numbers that will appear only on that extension. Quick Dial Keys allow the user to enter 6 names and numbers for quick access.

10
Page 10 Web UI – System Settings Basic Settings include assigning the operator extension, setting the system date and time (default is to access a NTP server) and setting the maximum time allowed for outside calls that have been transferred or forwarded to outside numbers. If a 4 line system has one outside call forwarded to an outside number and another outside call is transferred to an outside number, then all lines are now tied up with two calls. Ring Groups are set up to ring multiple extensions for a specific purpose, i.e. a number of extensions could be included in a ring group called Sales. This can then be accessed via the Auto Attendant when the caller hears “press 1 for sales.” Auto Attendant is a fully customizable system for answering and routing calls. Different greetings, prompts, routing and information can be presented for up to three scenarios; Day, Night and Lunch. Hold Message allows a message to be recorded and played for outside callers on hold. Many businesses use this feature to promote their company and or products while the caller is on hold. System Directory allows the administrator to enter up to 100 names and phone numbers that can be accessed by any extension.

11
Page 11 Web UI – Device Management Backup/Restore will back up the extension or system settings to a computer. The resulting files can be used to restore these settings in the event that a Deskset or Gateway is replaced or reset. Upgrade Device allows the administrator to check for available software updates and apply updates to any device in the system.

Page 13 The SB67030 Display Context- Sensitive Help Text The 4 keys below the display are Soft Keys, meaning that their function changes depending on the current activity of the Deskset, e.g., idle mode, on an active call or using functions such as MENU or REDIAL. The keys will perform actions associated with the current state as indicated by the functions displayed immediately above each key. Where there are more than 4 functions associated with a state, the forth key on the right changes views to display additional options. The upper 5 keys on the right side of the display are Call Appearance keys. They provide access to up to 5 simultaneous calls. The status of each Call Appearance is shown by the display icon aligned with the key, indicating Idle, Active Call, Hold, Ringing and so on. The bottom key in this set is the Quick Dial key as shown on the display. Pressing this key temporarily changes all 6 keys into one-touch dialing keys for quick access to your most important numbers.

Page 16 SB67030 Menu – User Settings Voice Mail Greetings – The user can record primary and alternate greetings which can be switched between different circumstances, i.e. in the office; out of the office. This saves the user from rerecording greetings every time their situation changes. Cal Forwarding – Calls can be set to forward after a number of seconds (user programmable) or immediately. The user also has the choice of sending the call to Voice Mail, another internal extension or an outside number.

17
Page 17 SB67030 Menu – Admin Settings Among the options under Admin Settings are: Forward/Transfer to an outside line – The administrator controls the ability of the system to forward and transfer calls to outside numbers. This is important because either of these features applied to a call from an outside party result in two lines being used for a single call. Software Upgrade – Allows the administrator to access AT&T’s server to check for and install the latest software
